Application med November 11, 1919. Serial 110. 337,257.

is a specification.

This invention relates to ventilating transoms and the object thereof is to provide such a transom with a plurality of louvers mounted to turn on their axes and an actuating bar carried by said axes and adapted to open and close the louvers at the will of the operator, means being provided to hold said bar in adjusted position.

Another object is to provide a slatted transom constructed to be burglar proof and yet thoroughly ventilate the room in oonvention.

In the accompanying drawings: Figure 1 represents a front elevation,

taken from the interior of the building, of

a transom constructed in this invention.

Fig. 2 is a transverse vertical section thereof taken'on the line 22 of Fig. 1'.

Fig. 3 is a similar view taken on the line 33 of Fig. 1.

Fig. 4 is a detail perspective view of one accordance with end of one of the louvers with the rod which forms its axis connected broken ofi'.

Fig. 5 is a similar view of a the actuating bar.

In the embodiment illustrated the transom constituting this invention is shown in therewith and portion of the form of a sash or frame F fixed stationary in an opening in theside wall S of a building. Mounted in the frame F is a plurality of louvers 1 preferably constructed of glass and each shown with a metal cap 2 on each end thereof. These caps 2 are each provided on one face thereof with a laterally extended boss 3 apertured from end to end longitudinally of the louver to receive a rod 4 which forms the axis of the louver. As stated above, each louver has a cap 2 on each end and the rod 4 extends through the apertures in the bosses on these caps and is fixedly connected therewith by set screws 5, although obviously these rods may be othersecured to the louversif found desira e.

The rods 4 extend longitudinally of the sash or frame F and are provided at their opposite ends with cranks 6, the terminals of which are pivotally mounted in bearings 8 on the outer face of the frame F at its opposite ends. Any desired numbers of louvers 1 may 'be mounted in the transom frame, six being here shown, three being ar' ranged at one end of the transom and three at the other end and separated by a partition strip F across which the rods 4 extend as is shown clearly in Fig. 1.

An actuating bar 7 is shown positioned at each end of the transom extending transversely thereof and through apertures 9 of which extend the crank ends 6 of the rods 4. One of these bars 7 is provided on its inner face with a laterally extending arm 10 having an eye '11 at its free end with which is designed to be engaged an operating rod 12 for moving the bar with which it is connected longitudinally'thereby rocking the rods 4 and opening or closing the louvers according to the direction in which the operating member is moved. While two bars 7 are shown, one only may be used. Between each of the bars 7 and the frame F are outwardly bowed spring metal strips 13 secured to the bars, two being here shown for each bar with their bowed portions positioned to engage the end members of the frame F for frictionally holding the bars in adjusted positions. It will thus be seen that these springs also operate through the bars to hold the louvers in adjusted position. While these springs 13 are shown located as above described, they may be otherwise mounted if desired provided they effect the holding of the louvers in adjusted position.

From the above description it will be seen that the louvers or slats 1 may be readily connected with or disconnected from their respective rods or axes by loosening the set screws 5, straightening out one of the crank ends and slipping ofl' the louver from the rod which may be replaced by another in case of breakage.

With the parts in the position shown will be seen that the crank ends 6 of the rods 4 are arranged at an angle of about 60 to the vertical which is the position assumed when the slats or louvers are closed and that they may be opened by a pull on the operating rod 12 and closed by an upward push thereon. It is, of course, to be understood that the slats while shown as made of glass may be of any desired material, glass being preferable to permit the entrance of light.

From the foregoing description taken in connection with the accompanying drawings the advantages of the construction and the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention together with the device which I- now consider to be the best embodiment thereof I desire to have it understood that the showing is merely illustrative and that such changes may be made as are within the scope of the claimed invention. v

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

l. A transom or the like composed of a frame having a rod arranged longitudinally thereof and provided with crank ends mounted to turn on the ends of said frame,

a louver carried by said rod, and an actuating bar mounted to move transversely of said frame and through which one of said crank ends extends.

2. A transom or the like composed of a frame having a rod arranged longitudinally thereof and provided with crank ends thereof and provided with crank ends mounted to turn on the ends of said frame,

a louver having metal caps on its oppositeends with apertured lugs projecting from one face thereof, said rod extending through said lugs, set screws securing the rod to the caps, an actuating bar mounted to move transversely of said frame and through which one of said crank ends extends, means for reciprocating said bar to rock said crank rod and an outwardly bowed plate spring carried by said bar and adapted to frictionally engage said frame to hold said bar and louver in adjusted position.

4:. A transom or the like composed of a frame adapted to be fixedly mounted in an opening, a plurality of rods arranged longitudinally of said frame and having crank ends pivotally connected with the ends of said frame, louvers carried by said rods to turn therewith, an actuating bar arranged transversely at one end of said louvers and through which the crank ends of the rods extend, an arm projecting laterally from said bar, and an operating element connected therewith.

In testimony whereof I have aflixed my signature in presence of two witnesses.
